Quick-action chuck (Quick Chuck)
WARNING
Risk of injury due to rotating parts
Before mounting/dismantling the quick-action chuck, switch off the device
and disconnect it from the power supply to prevent unexpected starting-up
of the device!
The quick-action chuck is pre-fixed on the stirrer shaft with a grub screw so that it cannot turn
and is locked on the stirrer by the safety ring (marked by the hatching in the following figure).
➜
Push the safety ring upwards to open the locking (figure left: safety ring in upper position):
– If the locking is open and the grub screw is loosened, the quick-action chuck can be
removed or inserted.
Inserting and locking the quick-action chuck
➜
Push the quick-action chuck onto the stirrer shaft so that the screwed-in grub screw
engages in the assembly hole of the stirrer shaft and the quick-action chuck can thus be
fixed securely (above figure, right).
➜
Use the hex wrench supplied to turn the grub screw clockwise, in order to fix the quick-
action chuck.
➜
Push the safety ring downwards to lock the quick-action chuck.
Tighten the grub screw by hand only and with the help of the hex wrench
supplied.
Make sure that you do not overtighten the grub screw, as this damages
the thread.
